Hi hoping for some help here, I turned off my boiler over xmas, came back turned it on and now it's no longer heating the store.
I've checked both off peak and boost, neither are warming, I've checked and tried to reset both thermostats on both elements, but they both seemed like they didn't need a reset. To be honest I'd be surprised if both top and bottom went at the exact same time.
The PCB board led is flashing twice every second, which say's normal operation according to the manual, and the pump runs. I've checked the fuse on the PCB and it's not blown.
Other things to check? Next steps?
